DCA1000EVM: Maximum Number of Targets

Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR1642BOOST

Hi, I am trying to determine the maximum number of targets an AWR1642BOOST and DCA1000 can record data for, but there is no documentation on the data size of each target or anything related to the maximum amount of data a system like this can record at the same time. I have the stock 8GB microSD card that the DCA1000EVM comes with. And I am also interested in determining the maximum number of targets a single AWR1642BOOST can view on your web based demo visualizer.

Thanks

    Hello Davis,

    DCA1000 just records the data being sent over the LVDS interface, typically raw ADC data is sent over this interface and not object data. There is no limit to the amount of the data you can capture from DCA1000, it streams all the data live over ethernet internal. Size of capture just depends on the PC you are using to store the data.

    If you want to view detected object data I would recommend using the standalone AWR164BOOST flashed with the mmwave demo application. This would send the object data out over the UART interface and you can use the mmwave visualizer to view it. I would recommend going through the mmwave SDK documentation to understand how the max number of detected objects, detection threshold etc. can be adjusted.  

    The microSD card support is not currently available on DCA1000.

    Hi,

    How do I determine the maximum size of capture for the PC I am using? Are there equations I can use from any documentation? I couldn't find anything that tells you the size of capture for individual objects.

    I used the mmwave demo application before, but we need the raw data to perform our own calculations. I am on the SDK documentation but I can't find anything on max number of objects detected.

    Is there a purpose to the microSD card slot on the DCA1000 then?

    Thanks

    Hello ,

      >>How do I determine the maximum size of capture for the PC I am using? Are there equations I can use from any documentation? I couldn't find anything >>that tells you the size of capture for individual objects.

    As I mentioned DCA1000 captures the raw ADC data and not object detection data. The  size of the ADC data would be equal to

    ADC bit size (12/14/16) * 2 (for complex) * No. of receivers *number of chirps per frame * number of frames.

    The amount of ADC data that you can capture with DCA1000 depends on the free disks space on the PC, which could go into GB.

    >>Is there a purpose to the microSD card slot on the DCA1000 then?

    Presently there is no purpose.
